This is just to confirm that I had the exact same issue and that this solution worked fine for me today!

Re:Yoga S740-14IIL USB-C to HDMI not working anymore

I bought my daughter a new Yoga C740-14IML laptop for Christmas (just over 1 month ago).

 

Was working fine with USB-C to HDMI for external monitor.  Then all of a sudden, no longer works.  I then connected other laptops (we have two other Lenovo laptops) to troubleshoot and the screen and adapter are fine.  In fact, I even bought a second adapter in case something was wrong with the first adapter.  But again still doesn't work (although new adapter works fine for my other Lenovo laptops)

 

I tried the solution posted in this thread (disconnect everything, hold power but for 60 seconds, plug back in) and it didn't work.  Tried it multiple times and still doesn't work.  Both USB-C seems to work fine for other things, such as connecting to the power cord.

 

Someone please help!  Is there an easy way to get a response from Lenovo Support?

I have done this a couple of times. Unlike so many other fixes, it actually works!!! My Lenovo C740 15 inch machine is working great and I am no longer having USB-C port issues. (Or, at least they are easily fixed if they happen again.) They seem to happen most frequently when I plugged in a device that drew too much power from the port. So, some unpowered hubs and ethernet adapters would frequently cause them to stop working. ) THANK YOU FOR THE FIX!!!
